Normal is a battery diagnosis service that suggests personalized actions you can take to extend your battery life. By aggregating data from hundreds of thousands of users, Normal is able to accurately and precisely pinpoint the battery hogs on your device, tell you whether or not this is also happening to other people, and project by how much time you will extend the battery by killing each hog.

Normal works by collecting generic usage data on your device over time—including what apps are running, what type of device you have, and the battery level—and aggregates it on our cloud platform. Normal then analyzes this data, along with data from all our other users, with proprietary statistical algorithms designed at UC Berkeley’s AMP Lab.
